ATT
(
FRONT END ATTENUATOR
)
The Attenuator will reduce all signals (and noise) by 10 dB, and it may be used to make
reception more pleasant under extremely noisy conditions. This feature is not available on
the 144 MHz and 430 MHz.

Function Row 7
[
IPO, ATT, NAR
]
appears on the display.
2. Press the
(

)

of the “ATT” indication.
3. Press the
(

key once more to switch the Attenuator out of the receiver front end
circuit.
AM/FM DIAL
In the AM and FM modes, the knob is locked out (via the setting of Menu #04) so as
to allow “channelized” tuning on these modes. To adjust the operating frequency, rotate the
knob.
If you wish to enable the knob for tuning in the AM and FM modes, change the setting
of Menu #04. See page 60 for details.
The “channelized” mode of tuning on AM and FM automatically rounds off the
frequency to the next “logical” step when you rotate the knob one “click” in
either direction. This eliminates the inconvenience of having to preset the frequency to
an “even” channel.
